JANET JACKSON was hospitalized in MONTREAL yesterday due to an undisclosed illness. Suddenly falling ill during soundcheck, it was decided that she couldn't go on minutes before LL COOL J was about to open the show. Her illness has also prompted the cancellation of a concert in BOSTON TOMORROW (10/1).

A spokesperson for JACKSON would only say that the singer is now doing "okay," but would not speculate on when she would return to her first tour in seven years. Coincidentally, JACKSON also can celled her DETROIT show last Friday, due to "production constraints," according to TMZ.COM.
